ABSTRACT:
To reliably discriminate a slight collision from a serious collision or vice versa by use of only a single shock sensor, the air bag ignition control system for an automotive vehicle comprises a deceleration sensor, a low-pass filter, and a CPU provided with functions for calculating a vehicle speed information value B and a collision mode information value E both on the basis of deceleration detection signal, and an ignition decision information value F on the basis of the two calculated information values B and E. The CPU generates an air bag ignition signal when the calculated ignition decision information value F exceeds a predetermined value K. In practice, since the system can be mainly configured by low- and/or band-pass filters and a CPU, it is possible to simplify the system configuration, markedly.
